Turns out I was a bit quick on the send button, and having been focused on the
failing test_checksums suite I missed running the other suites.  (I also
managed to off-by-one-year name it 202503..) Thanks to some quick off-list
feedback, here is an updated version which fixes the failing tests and has
quite a number of smaller touchups.

Like the previous version, I am not sure I have the CHECKPOINT_xxx logic right
and would love some eyes on it.
